Be it known that I, JACOB It. FnrrznoUs,

i of Indiana,.in the county of Indiana and State of Pennsylvania, haveinvented la new and valuable Improvement in Hay-Elevators; and I do`hereby declare that the following is a full, clear, and exactdescription of the construction and operation ofthe same, referencebeing had `to the annexed drawings making a part of this specification,and to the'letters and figures of reference marked thereon.V Y

Figure lof' the drawings is a representation` of ila 4sectional view otmy hay-elevator, rand Fig. 2 is a sideview of the same.V Fig.

3 is a detail view. n

This inventionlhas` relation to devices which aredesigned for; elevatinghay from wagons, and delivering the loads upon mows in barns', whereinthe elevating-fork is attached to a .pulleyl suspended from acarriagewhich-is movable on abar `or beam located at or near the `top'of the barn, so. that when a load is ,raised to the proper height itcan be easily `moved `to a place for discharging it. Then'at're of myinvention V consists 11n the novel construction and arrangement of theParts, @Slll'enafter more fully described andclaimed. i l

. L, In the 'annexedw"drawing,- A A' designate 7 .the roof-timbers of abarn, to Which are secured the endsof around bar, B, which Idenominatethesupporting-bar, as it is `upon this bar th atthe carriageof the elevator travu els.'` C desigratesthe carriage, which isoi`triangular ibr`mtl'1e upper angles ofthe trian` gle being'connectedtogether by means of two rods, whichserve as axles for twodeeplygrooved wheels,a `a.' vThese wheels a a roll` i upon theba-r B,and allow the'carriage-fraine `b to' be swunglaterally Vwithout anyliability .of

the said wheels being detached from their i bar. The lowerpart oi'thecarriage C carries a groovcd pulley, c, around which anelevating-rope, `g, p`asses." One end of this rope `g e is secured tothe fra-me b of the carriage U,

I and the other end of the'rope -may be passed over a pulley, p, locatedVat or near the rooftimber` A'. From this rope is"suspe1nled a l lpulley-block, h', carrying a pulley, p, and hav-V ing secured toits-lower end a l|ook,., to'which is attached a forkof suitabledescription, with a tripping device for it. E designates a stirrup,which is pivoted at c to one end of wa le; ver, D, and which hangsfreely from this lever, so as to always assume such a position that,when the load is raised to its fnll height, the said pulley-block h'will raise the stirrup E, and with it one end of the lever D. This leverD is pivoted at i to anA oiset of the frame adaptedto engage with acatch, G, which .is adjustably secured tothat end of the bar Bfromfwhiohthe load is elevated from awagon. This catch Geisthe half of aconcave conethat is to say, it is tapering from a concave i base, andlaterally convex-and presents av semicircular catching-lip, j. The catchthus described is securedA to a teat or stop, k, by means of n'uts andbolts, or bolts alone, which are lettere-dm m in Figs. 2 and 3. `Thestop k presents a `concave edge, j, towardthe ear"- riagc C, and thisstop isr so arranged, kwith refer- .ence to the catch G, that thecarriage will be varrested by said stop k at the same time the hook fengages with this catch.-

It will be seen from the\ above description 'that the catch G, being.laterally rounded,

will allow the hook fof lever D to engagewith it whatever may be theangle of inclination `given to lthe carriage C. Also, that the carriageis arrested by a stop,fk, whenthehook fengages with the catch G.'

l The catch and stop, thus made separately, 'and connected together, canbe easily adjusted on the supporting-bar 'to any point or position bysimply loosening the bolts. 'i It will be furthermore seen that thelever D serves not only to hold the carriage V in its properpositionwhile the load is being elc- .\atccl, but that'when the load iselevated to its highest point, and the pulley-block i'vtrps' the ropeand prevent thedescent of theload.

t saidlever, it (the leierl D) will vdrop upon the Y rope g, and', byits toothed portion d, gripe Heretofore it has been customary topermanently seeurethe catch and stop to the barnbeum, for engagementwiththe hooked lever of the movable carriage but my improvement consistsin constructing the catch andstop in two'separate and movable pieces,ybolted to gether around the beam, whereby they can be.

easily adjusted yand removed without interfering with the barn-beams orthe operation of the carriage. t o

=Wha-t I claim as new, and"A desire to secure by Letters Patent, is-

:rne adjustable. ana removern catch e, n periug' and laterally rounded,and having a lipped` bese, and which -is separately con structed fromthe wheel-stop k, and applied to bar B, and secured thereto by meansv ofboltsand nuts passing through the stop. k and catch G, in combinationwith a hooked clutching-1evere D, substantially as described.

In testimony 'thatI claim the above I have 'hereunto subscribed my namein the presence `Nifitnesssesr GEORGE Row,
